Description

This section uses alternating challenge styles to show how to use CSS to position elements in a flexible way. First, a challenge will explain theory, then a practical challenge using a simple tweet component will apply the flexbox concept. Placing the CSS property display: flex; on an element allows you to use other flex properties to build a responsive page.

Instructions

Add the CSS property display to #box-container and set its value to flex.

Tests

tests:
  - text: <code>#box-container</code> should have the <code>display</code> property set to a value of flex.
    testString: assert($('#box-container').css('display') == 'flex', '<code>#box-container</code> should have the <code>display</code> property set to a value of flex.');
